i BOTTLE.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed January 3, 1907, Serial No. 350,583. Renewed February 11, 1908. Serial No. 415,368.

To all whom it may concern:

Be it known that I, REUBEN R. GRAVES, a citizen of the United States of America, residing at Salem, in the county of Marion and State of Oregon, have invented new and use ful Improvements in Bottles, of which the following is a specification.

My invention has relation to improvements in bottles, and it consists in the construction and arrangement of parts as will be hereinafter described and particularly pointed out in the claim.

A bottle constructed in accordance with my invention is shown in the accompanying drawing, in which Figure 1 is a central vertical section through the neck and upper portion of the bottle body showing the neck sealed by my improved closures. Fig. 2 is a top plan view of the guard.

The body 1 of the bottle or receptacle may be of any preferred form and is provided, as usual, with an upwardly extending neck 2, which is integral therewith. The bottle as a whole may be formed of glass or any other suitable material, and, in accordance with my invention, the neck 2 is formed at a suitable distance below its upper end with an annular external groove 3, leaving a thin web or reduced portion 4 connecting the upper portion of the neck with the lower portion thereof. The part 4 constitutes a frangible portion by which the upper portion of the neck may be readily and conveniently separated from the lower portion for the purpose of extracting the cork and discharging the contents of the bottle, as hereinafter described.

The neck is designed to be closed by a cork or other stopper 5, which extends partly above and partly below the frangible portion 4 and reinforces the same so as to prevent breakage of such portion in the ordinary handling of the bottle. An annular shoulder 6 is formed upon the interior of the neck below the portion 4 and forms a stop to prevent the cork or stopper from being inserted too far, thus adapting said shoulder to serve as a gage in the application of the stopper to a correct position. A guard 7 is arranged above the stopper and comprises a bowl-shaped metallic disk slitted radially at diametrically opposite sides, as indicated at 8, to adapt it to expand and contract to a limited degree. This guard is inserted with its bottom portion or convex face downward into the neck and rests centrally upon the upper surface of the stopper, the edge of the disk projecting into an annular groove 9, whereby said guardis effectually fixed in position.

After the bottle has been initially filled,the stopper 5 is inserted in position to seal the neck 2, and then the guard 7 is forced clownward into the upper portion of the neck. As the guard is made of spring metal, the slits 8 therein permit it to contract until the edge of the disk comes into register with the annular recess or shoulder 9, whereupon the disk will expand, and the edge thereof will be projected into said recess, thus locking the disk in place against any possibility of withdrawal without breaking or otherwise mutilating the neck. Owing to the fact that the concaved surface of the disk is exposed, the disk cannot be grasped by the use of extracting tools and its removal effected without breaking the neck. Security is thus afforded, as the guard and stopper cannot be withdrawn without giving visual evidence of the fact that the bottle has been tampered with. When it is desired to discharge the contents of the bottle, the upper portion of the neck is struck against or by some hard object, thus causing it to break at the weakened portion 4. By this means the upper portion of the neck will be severed from the lower portion, leaving the cork exposed so that it may be extracted. At the same time the removal of the upper portion of the neck will render it evident to the observer that the bottlehas been once filled and opened. By the arrangement of the weakened portion below the top of the stopper, any possibility of small particles of glass passing into the lower portion of the neck during the operation of opening the bottle will be prevented, as Will be readily understood.

I wish it to be understood that I provide the neck of the bottle with a surrounding annular reinforcing bead 10, which is arranged below the upper surface of said neck and in alinement with the groove 9, said bead serving to compensate for the weakening of the neck especially in connection with the groove 9. I wish it to be further understood that one portion of the neck is provided with a straight cylindrical part at the terminal of which is formed the shoulder 6, this construction of the straight portion of the neck permits of the cork having a through passage to the shoulder without obstruction. Further the dished disk guard serves to hold the cork in contact with the shoulder.

Having thus described the invention, what is claimed as new, is:

A bottle having a portion of its neck constructed in straight cylindrical form and terminating with an annular shoulder, an annular reinforcing bead next to the upper end of the neck, said neck having an internal annular groove arranged in alinement with the bead, a weakened portion arranged midway between the shoulder and bead, a cork stopper mounted in the straight portion of the neck so as to extend above the said weakened per 15 as to keep the lower surface of the cork in 20 contact with said shoulder, substantially as specified.

In testimony whereof, I affix my signature in presence of two witnesses.
